BED-LIFTER.

Specification of Letters Patent.

Application filed August 7, 1911.

Serial No. 642,737.

To all whom it may concern:

Be it known that we, JOSEPH S. VIsoER and CHRISTIAN CLAUs, citizens ofthe United States, residing at Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Improvements inBed-Lifters; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invent-ion relates to improvements in bed lifters, and moreparticularly to means for lifting either end of a bed to place the samein a position higher than the opposite end.

An object of the invention is to provide mechanism which may be used ateither the head or the foot of a bed and manipulated to raise that endof the bedstead.

Another object is to provide a lifter of this character which may bereadily at tached to, or disconnected from the bedstead, and a furtherobject is to provide a device of this character which may be readily andeasily operated to adjust the height of the end of the bedstead inrelation to the opposite end.

Other objects and advantages will be apparent from the followingdescription taken in connection with the accompanying drawings, and itwill be understood that changes may be made in the specific structureshown and described without departing from the spirit of the invention.

Figure 1 is a perspective view of the bedstead showing the lifterattached to the head thereof, said head being slightly raised. Fig. 2 isa side view thereof, Fig. 8 is an elevational view of the lifterdetached from the bed, and Fig. 4 is a cross sectional view on the line44 of Fig. 1.

In the drawings 1 represents the hollow posts which are connected by thehorizontal brace bar 2 connected near the opposite ends of said hollowposts and working slidably within the hollow posts 1 are the smallerpipes or hollow posts 3 which are internally threaded to receive thethreaded rods 4, the upper ends of which have secured thereon thesprocket wheels 5. The upper extremities of the rods 4 are reduced andmounted in the blocks 6 which latter are secured to the upper horizontalbrace bar 2 by means of screws 7 or other suitable means passed throughsaid brace bar and into the blocks 6.

At the points at which the blocks 6 are secured upon the upperhorizontal brace bar 2 the latter is enlarged and flattened, as shown at2, to form suitable seats upon which the blocks may rest, thuspreventing loose play at these points of connection. It will beunderstood that the blocks 6 are suitably cut away to accommodate thesprocket wheels 5. WVorking over the sprocket wheels 5 is a suitablechain 8 which may be readily moved in either direction to raise or lowerthe pipes 3 within the hollow posts 1 by rotating the rods 4. The pipes3 are prevented from rotating by means of the pins 9 carried thereby andprojecting through suitable guide slots 10 arranged longitudinallywithin the hollow posts 1, the guide slots 10 limiting the verticalmovement of 4 the pipes 3 in either direction.

The lifter is secured either to the head or foot of a bed by means ofthe clamp arms 11 which are arranged in pairs, each pair of arms beingdrawn together by a clamping screw 12 working in threaded openingsthrough the central portions thereof, the large ends of the arms partlysurrounding and tightly gripping the hollow posts 1, while the smallends thereof are engaged partly around the posts of the end of the bed.It will thus be seen that as the sprocket chain 8 is moved in onedirection the sprocket wheels 5 will be rotated to revolve the screwthreaded rods 4 and thuscause the hollow pipes 1 to move upwardly uponthe posts 3, raising the adjacent end of the end to which it isconnected in respect to the opposite end of the bed, making it possibleto tilt the bed as desired.

It will be evident that this lifting appliance may be applied topractically any type of bedstead, and will effectively perform itsduties and will raise the end of the bed gradually without causing anyjar whatever. This is especially desirable in hospitals where it isoften necessary or desirable to place the head or feet of the patient inan elevated position. It will also be apparent that this bed lifter maybe cheaply manufactured owing to the comparatively small number of partsof simple formation.

hat we claim is: l. A bed lifter comprising hollow posts, means forconnecting the posts, means for securing the posts to the bed,internally threaded pipes within and extending through the lower ends ofsaid posts, and

means for moving the posts longitudinally 1gippn the pipes to vary theheight of the 2. A bed lifter comprising connected hollow posts, pipeswithin the hollowed posts, said posts being adapted to be movedvertically upon the pipes, means for securing the connected hollow poststo the end of the bed, means for moving the posts vertically to raise orlower the end of the bed, and means for limiting the vertical movementof said posts in either direction.

3. A bed lifter comprising a framework including hollow posts, pipeswithin the posts and projecting through the lower end thereof, rodsprojecting through the upper ends of the posts and extending into thepipes within said posts, connections between the upper ends of the rodsto rotate the same and move the posts upon the pipes to vary the heightof the lifter, means for limiting the movement of said posts and meansfor securing the framework to a bed.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
